[REQUEST] A Discord Nitro Code checker?

So I coded a discord nitro code generator a few months ago (posted on my account) but I don't have a checker for it, can anyone help me with a checker? I want to get a checker for the codes i make, preferably one which is fast (since i got millions of codes just lying with me and i want to spend as little time on it as possible)


Thank you in advance
